COB/A BRAITHWAITE BATTIN, OF MOUNT VERNON, NEW YORK.

FASTENING nnvron.

Application filed. June 4',

T 0 all whomit may concern. v

Be it known that I, Conn BRAITIIWAITIJ BATTIN, a citizen of. the United States, and resident of Mount Vernon, county of Westchester, State of New York, have invented certain new and useful Improvements in Fastening Devices, of which the following is a specification. I

This invention relatesto fastening. devices and has specific reference to such devices as are particularly adapted to be used as a means for fastening together the folded or overlapping corners of a bed sheet so that the same may be effectively held or re-. tained upon a mattress.

An important object of the invention is to provide a fastening device of the above mentioned character which may be easily applied to the folded or overlapping corners of a bed sheet or the like and when so applied may serve to retain the corners of the sheet in an overlapped or folded relation in such a manner as to effectively retain the sheet upon the mattress.

A further object of the invention is to provide in a device of the above mentioned character a means by which more or less of a gripping action will be exerted upon the sheet in order to effectively retain the device in position when applied.

Another object of the invention is to provide a fastening device of the character mentioned which is simple in construction, strong, durable and reliable in use.

Other objects and advantages of the invention will appear when considering the following specification in connection with the accompanying drawings, in which [Figure 1 is a perspectiveview showing the device embodying my invention applied to a bed sheet, the corners of which are folded over the corner of a mattress.

Figure 2 is a plan view of the device- Figure 3 is a longitudinal sectional view taken on line 3-'3 of Figure 2.

Figure at is a fragmental view of the plate showing the normal position of the gripping element.

In the drawings wherein is shown the preferred form of my invention, the numeral 5 indicates a 'mattress having thereon a sheet 6 which is folded over the corner of the mattress and under the same. The folded portions of the sheet 6, when'placed upon the mattress 5 as described, are adapted to be retained or fastened together Specification of Letters Patent.

in a folded relation by means of the device embodying my invention, which comprises a plate 7 bent intermediate its ends to provide a relatively long bowed portion 8 and a relatively short bowed portion 9, the bowed portion 9 being projected in an opposite direction to that of the bowed portion 8- as clearly shown in Figure 3. The plate 7 is constructed from a suitable metal having more or less resilience in order that the gripping element 10, which is a continuation of the bowed portion 9, may exert more or less pressure upon the piercing end of the retaining pin 11 which is passed through the perforations 12 formed in the plate 7 at the ends of the bowed portions 8 and 9. It will be noted from Figure 41- that the gripping element 10 is bent to such a position, with respect to the bowed portions 8 and 9 of the plate, that its end lies normally in the path through which the pin 11 passes when inserted through the perforations 12. It is apparent that when the piercing end of the pin 11 moves by the gripping element 10, this element will be sprung from its position shown in Figure 4 to the position thereof shown in Figure 3, and that due to the resiliency of the grip ping element more or less pressure is exerted thereby upon the pin 11. It is due to the gripping action of the gripping element 10 that the device as a whole is securely retained in position when applied as shown in Figure 1, the material being gripped bctween the pin 11 and the gripping element 10 as clearly shown in F igure 3.

The pin 11 is preferably provided with a cross-bar 13 in order to limit the distance to which the pin is inserted, and in order to enable the pin to be readily removed, I prefer to provide the same with an extension 14; which at its end carries a head 15.

While I have shown and described a preferred embodiment of my invention, it is obvious that various changes in the size, proportion and detail construction of the same may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A fastening device comprisin a plate bent intermediate its ends to provide oppositely bowed portions, said plate being provided with a series of erforations, and a pin passed through said perforations, said pin being so disposed when passed through said perforations as to bridge each of said bowe portions, the bowed portions being spaced intermediate their ends from said in. I

2. A fastening device comprising a plate bent intermediate its ends to provide bowed pin adapted to be passed through said perforations and to receive the thrust .exerted by said gripping element when said pin is disposed in sald perforations.

i. A fastening device for securing together overlapping portions of material comprising a plate bent intermediate its ends to provide bowed portions one of which terminates in a gripping element, said plate being provided with perforations, a pin adapted to be passed through the material and said perf0rations,a portionof the Inaterial being gripped between said pin and gripping element.

In testimony whereof I have aflixed my signature to this specification.
